Application filed November 10, 1924. Serial No. 748.921.

This invention yrelates generally to `the washing machine industry, and particularlyv to that class of Washers which are especially adapted for use in the home. The 'first object of my invention is to provide an exceedingly simple and efficient Washing machine which will greatly facilitate `the Washing, rinsing and bluing of clothes.

`The second object is to employ a special Aarrangement of vacuum cups, or pounders, wherein :both operations of Washing and rinsing can be carried on :at the same time, or one foperationcan be carried on in two places at one time, thereby permitting one lot of clothes to be rinsed While a successive lotfis being washed, instead of causing the operator to Wait between batches or to drag the washing operation over a long space of time, during which a great deal of heat is lost from the water employed.

The third object is so to construct the inachine that the mechanisms of both sections areopposed in a-manner-to hold the parts in a perfect state of balance at all times, thereby greatly cutting down the current consumption.

The fourth object is to employ the minimum 4number of gears and parts in the con- 3f? struction of the machine and to use only such standard gears as are commonly found in the various lines of machinery, and to operate-these gears in an oil bath.

The fifth object is to so construct the inachine that it Will readily lend itself to the cheap manufacture and assembly of parts.

The sixth object is to so `arrange the companion parts that the Wringer employed need not be swung or moved out of position.

I :accomplish these results in the manner set forth in the following specification and illustrated in :the accompanying drawings, in lwhich:

Figure 1 isa side elevation of the entire machine of Which Figure 2 is a front elevation. 'Figure 3 is a horizontal section taken along the line StB in Figure 1. Figure 4 is a horizontal section taken along the line 4-4 in Figure 5. Figure 5 is a vertical section taken along the line 5-5 in Figure 4. Figure 6 is a vertical section taken along the line (5-6 in Figure 4.

Similar numbers of reference refer to the saine parts throughout the several views.

eferring in detail to the drawings, I have illustrated a frame consisting of the CII legs 10 and the cross ties 11 12, 13 and 14. asters are placed under the ylegs l0. j `Supported on the cross.. ties 12 are the Waiter containers comprising lthe fioor 16, `U0

side Walls 17 and dividing partitions 18. A

W-ringer 19 is permanently secured over the partition 18, and covers 20 and 21 are removably placed over the separate compartments on opposite sides of the Vwringer 19.

On the cross ties 11 is `mounted a housing comprising a bottom 22, side Walls 23 and a cover 24. The housing itself is somewhat in the form of a cross Whose opposite-ends 25 and 2G are 'i' shaped and Whose remain- 7 ingopposite ends 27 and 28 are L shaped.

In that portion of the housing between the ends 25 and 26 are `placed the bearings 29 and 30 and also 31 and 32. A sleeve 33 journals in the bearings 30 and 81 and has 75 formed thereona flange 34. A Wormwl'reel 85 is secured on the sleeve 33 bet-Ween the flange 34 and the Abearing 30. The. ends of thev sleeve 33 are `provided with jaws 36 and 37, each of lwhich vconsists of one-half of the sleeve ends. In each of the bearings `29 and 32 journals Va hub of the cranks 88.01 39. The shaft 40 `is secured to the crank `38 and journals in the sleeve 33.

A collar 41 Vis pinned tothe shaft 40 -and 35 a slidahle clutch collar 42 is :adapted toengage the jaw 3G of the sleeve 33. The shaft 43 journals in the sleeve 33 and `in `the hub of the Crank 39. Acollar 44 is pinned on the shaft 43 and Wears against the bearino -90 82. A clutch collar 45 is slidably mounted on the shaft 43 Vand can engageJ the jaw 37 ofthe sleeve 83. r

.On each ofrthecranks 38 and 39 `is placed a pin 46 which `can move in the slot v47 inthe yoke 48 which guides on lthe rods 49, which, in turn, are mounted on 'the floor of the housing. A plunger 50 is secured to the upper end of each yoke 48 and passes up- Wardly through the floor v16- and the stufiing box 51 and has mounted on its upper end a cross arm 52 to which are attached the pounders or vacuum cups, which may be of any desired type, but preferably along the line indicated in my Patent Number 1,557,270. A hole 54 of sufficient size to form a free passage for the lubricant should be provided under the bearings 29 and 82.

ln the cover 24 are mounted the hand levers 55 and 56 on the shafts 57'. The shafts 5T are provided with clutch collar engaging arms 58 which engage the collars 42 and 45.

In order to give` the necessary stiffness to the cover 24, ribs 59 and 60 are provided.

A motor 61 is mounted on the angle irons 62 and through the universal joint 62A drives a shaft G3, which passes through the stufl ing box 64 on the plate 65 which is secured. to the housing wall 23.

The shaft 63 passes into the elbow shaped end '128 of the housing and has secured thereon a bevel pinion G5 which meshes with the bevel gear 66 on the motor driven shaft 57, which ournals in the bearings G8 and 69. A collar 69A is pinned on the shaft 67. A worm 70 on the shaft G7 meshes with the worin wheel 35. A sei-ond worm 7l on the shaft 67 meshes with the worm wheel 72 on the wringer shaft 73 which transmits power to the wringer rolls through the. gear box Tet in the customary manner. y

The operation of my. device is as follows: Clothes are placed in the water containing compartment and its control lever or 55, as the case may be, is pushed over to cause its clutch to rotate its related crank, which, in turn, will cause theI pounders 53 'to inove upwardly and downwardly at an appropriate speed, assuming, of course. that the inotor 6l is operating. l

lVlien it is desired to rinse this lot of clothes, the covers Q() and El are. lifted otl' and the clothes are wrung` into the next coii'ipartment under the control of the lever 74A, and more clothes are placed in the first compartment. Both sets of pounder-s may now be employed, but only in a direction opposite to each other. Herein lies the secret of the low power consumption of this ina.- chine, sincethe load is made remarkably uniform by this arrangement and does not cause frequent drops in motor speed7 with correspondingly larger current consumption.

linsing water may be replaced by bluing water, or both sections can be employed for rinsingor washing or bluing as may be desired.; thereby greatly cutting down the total amount of time required by the operator to completely wash a lot of clothes, and also reducing the amount of heat requiredv for the operation by reducing` the amount of time during which heat can radiate from the nashing water. then wringing the clothes out to dry, the covers 2O or 21 are put in place to catch the clothes from theiwringer instead of letting them fall into the next compartn'ient.

lt will be observed thatfno matter how careless or inexperienced theoperator may he that the pounders will always oppose each other, owing to the nature of the jaws 36 and 3?.

l am aware. thatinany forms of washing machines have been constructed in the past, l therefore do not claim such devices broadly but have directed my claims to a special form of machine and a unique mechanism for operating saine, as set forth in the following claims:

l claim:

1. A drive for washing machines having, in combination, a. cross shaped housing', one pair of opposite' ends of said housing having L shaped ends and the other pair of opposite ends having T shaped ends; a crank in each of said T shaped ends; a split shaft supporting said cranks; a motor; a inotor drive shaft extendingr between said L shaped ends; a worin on the middle of said.

ictor' drive shaft for driving said split shaft; anda wringer drive shaft journaling in one of said l. shaped ends and receiving power from said driven shaft and transferring saine to an overhead wringer.

A drive for double plunger washing naufhines having, in combination,y a housing; a `motor mounted alongside of said housing; a drive shaft projectingfrom the motor shaft into said housing; a motor driven shaft journaling in said housing and geared to said drive shaft; a worm on one end of said motor driven shaft; a wringer shaft journaling in said housing; a worin wheel on the lower end of said wringer shaft meshing with said worin; a second worin near the middle of said'inotor driven shaft; a split transverse shaft over said second worin.; a clutch on each portion of said split shaft, each clutch having a single jaw; a sleeve on the adjacent ends of said split shaft having a single aw at each end thereof adapted to be engaged by eitheil of said clutches in ainanner that the two ends of said. split shaft will always have the same relation when driven by said sleeve; a worin wheel secured on said sleeve and meshing with said second worin; a crank on each end of said split shaft; a slotted yoke alongside of each crank; a guide for each yoke; and a plunger attached to each yoke.
